Energy policies relating to alternative energy

Current energy policies are still based heavily on natural resources. Meanwhile, the trend is increasingly toward alternative resources, such as wind power.

It's only a matter of time before natural resources, such as petroleum, are depleted. Petroleum, a fossil-based energy source deposited across millions of years, is used to produce fuel or electricity. Taking stock of the fact that 260 billion barrels (one barrel = 159 liters) of oil were extracted over the last 11 years, it's evident that the world's petroleum resources will be depleted one day. New developments in solar or wind power are aimed at providing alternative energy sources that will enable us to maintain our current standard of living. Petroleum is also required by the chemical industry to manufacture special plastics.

The advantages and disadvantages of alternative energy sources

When discussing the subject of petroleum and alternative energy, one must bear the advantages and disadvantages in mind. Our resources are running short . Because we cannot count on petroleum for the future, there will come a time when everyone will rely on the efficiency of wind power and other alternative energy sources . Unlike petroleum, wind power can be managed to ensure that it constantly renews itself. Wind power meanwhile makes it possible to have enough resources to supply entire cities. Petroleum has the additional disadvantage of harming the environment through CO2 emissions. This has resulted in increasing demand for resources such as wind power. Wind power can be classified into different categories. A class 4 wind turbine can meanwhile provide resources in a much more efficient manner than petroleum resources for instance. In addition, unlike petroleum, resources such as wind power offer a decentralized energy supply. This means that in contrast to petroleum, the utilization of wind power does not require a large power plant. Instead, it makes "transporting" the energy easier and faster. Decentralized wind power entails a massive infrastructure change. Resources such as wind power certainly bring disadvantages when it comes to the environment, although they pale in comparison to the disasters that can result from petroleum. The utilization of our resources determines how we continue to maintain our standard of living. This makes it important to continue public discourse on the issues of wind power and petroleum.

Resource shortage

It's only a matter of time before there is no petroleum left. For this reason, from a resource standpoint we should already be moving toward heavy reliance on wind power instead of petroleum. After all, from a pure scientific point of view, new petroleum resources won't be available for millions of years. Unlike petroleum, wind power is a resource that will never run dry. In Germany alone, wind power is serving as a popular alternative resource to petroleum. The demand for wind power will increase in line with the consumption of petroleum. For this reason, it is imperative that we gradually move away from petroleum and make more use of wind power or other alternative energy resources. The environmental pollution caused by petroleum is reason enough for an environmentally-conscious society to use solar or wind power. In contrast to petroleum, wind power is significantly better for the environment and offers a unique resource balance.

Blue OLED on Silicon Sensor detects Phosphorescence

The Fraunhofer FEP has been involved in the development of OLED-on-silicon sensors for years. The researchers have recently developed a miniaturized phosphorescence sensor that combines a marker and sensor on a very small chip surface that could be produced at low cost in the long term. Researchers will present the first prototype of the sensor, which is currently designed for oxygen ratio monitoring, at embedded world 2019.

In the course of digitalization and increasingly comprehensive monitoring of processes, automated workflows, also in biomedical and environmental engineering,...

New Material to Push the Boundaries of Silicon-Based Electronics

The electronics market is growing constantly and so is the demand for increasingly compact and efficient power electronic systems. The predominant electronic components based on silicon will in foreseeable future no longer be able to meet the increasing industrial requirements.This is why scientists from the university of Freiburg, the Sustainability Center Freiburg and the Fraunhofer-Gesellschaft have joined forces in order to explore a new material structure that may be better suited for future power electronics.

The recently launched project »Research of Functional Semiconductor Structures for Energy Efficient Power Electronics« (in short »Power Electronics 2020+«)...

Tandem Solar Cells – Record Efficiency for Silicon-based Multi-junction Solar Cell

Silicon solar cells dominate the photovoltaic market today but the technology approaches the theoretical maximum efficiency that can be achieved with silicon as the only absorber material. Tandem solar cells, on the other hand, combine several absorber materials, enabling a better energetic use of the solar irradiance spectrum. Due to their higher efficiency potential, tandem solar cells have a promising future. After intensive research, scientists at Fraunhofer ISE in cooperation with partners have achieved a new efficiency record of 22.3 percent for a multi-junction solar cell made of silicon and III-V semiconductor materials.

The outstanding achievement is that the III-V layers were directly grown on the silicon.

Better Protection for Power Converters During Turbine Operation

Power converters are among the most frequently failing components of wind turbines and are thus associated with high costs and long downtimes. A better understanding of the causes of their failure is vital for developing effective protective measures and thus improve the profitability of turbine operation. A project consortium composed of operators and manufacturers of turbines, semiconductors, and converters is working closely together with research partners in the project ReCoWind, funded by the German Federal Ministry for Economics Affairs and Energy. Field data from various sites and turbine types are being analyzed, damage models derived, and experimental tests performed on components.

Economic losses of around € 200 million per year arise in Germany alone due to repair costs and revenue losses resulting from failed power converters in wind...

Im Focus: Energy-saving new LED phosphor

The human eye is particularly sensitive to green, but less sensitive to blue and red. Chemists led by Hubert Huppertz at the University of Innsbruck have now developed a new red phosphor whose light is well perceived by the eye. This increases the light yield of white LEDs by around one sixth, which can significantly improve the energy efficiency of lighting systems.

Light emitting diodes or LEDs are only able to produce light of a certain colour. However, white light can be created using different colour mixing processes.

Im Focus: Quantum gas turns supersolid

Researchers led by Francesca Ferlaino from the University of Innsbruck and the Austrian Academy of Sciences report in Physical Review X on the observation of supersolid behavior in dipolar quantum gases of erbium and dysprosium. In the dysprosium gas these properties are unprecedentedly long-lived. This sets the stage for future investigations into the nature of this exotic phase of matter.

Supersolidity is a paradoxical state where the matter is both crystallized and superfluid. Predicted 50 years ago, such a counter-intuitive phase, featuring...
